SIMM

A SIMM, or single in-line memory module, is a type of memory module containing random-access memory used in computers from the early 1980s to the late 1990s. It differs from a dual in-line memory module (DIMM), the most predominant form of memory module today, in that the contacts on a SIMM are redundant on both sides of the module. SIMMs were standardised under the JEDEC JESD-21C standard.

Most early PC motherboards (8088-based PCs, XTs, and early ATs) used socketed DIP chips for DRAM. As computer memory capacities grew, memory modules were used to save motherboard space and ease memory expansion. Instead of plugging in eight or nine single DIP chips, only one additional memory module was needed to increase the memory of the computer.

History

SIMMs were invented in 1983 by Wang Laboratories, who were granted a patent in April 1987. The original memory modules were built upon ceramic and had pins, i.e. single in-line package (SIP) packaging. Later the modules were built on standard PCB material. Perhaps because the pins often bent or broke during installation, or were more expensive to manufacture, vendors replaced the pins with edge connectors. SIMMs using pins are usually called SIP or SIPP memory modules to distinguish them from the more common modules using edge connectors.
